Solar Light’s NIST-Traceable PMA-Series Digital Sensors represent the pinnacle of accuracy, durability, and selection on the market today. Our sensors measure discrete bands of the electromagnetic spectrum from the UVA, UVB, UVA+B, UVC, Visible Light, and Infrared regions. Both narrow and broad bands are available to fit any application, including germicidal requirements, environmental probes, and sensors for biologically weighted spectra (such as the erythema and CIE action spectra.) Over 135 different sensors are available in a variety of packages to fit any environment, from indoor clean rooms to harsh locations outdoors to 100 meters under water. Please note that Solar Light offers both Digital Sensors and Analog Sensors in the PMA-Series lineup. Select these Digital Sensors if you prefer to plug into our PMA-Series Radiometers to read the output of the sensor on the meter’s display. Digital models are typically used as discrete sensors that are portable and located to provide short term information. (By contrast, please select Analog Sensors if you don’t need a digital display output of the reading, if you will be connecting to your own datalogger, or if you plan to use a voltage source to provide excitation voltage to the sensor and a digital volt or amp meter to read and convert the results. Analog Sensors are typically used as process sensors that are permanently installed to provide ongoing information.)
